It would be great if you could narrow that down a bit. The r600g driver doesn't use LLVM, so that's probably not it. I agree it's most likely between Mesa or the kernel, or maybe xf86-video-ati. > Glamor is not in use. Have you tried glamor to see if it happens with that as well? Does Option "ColorTiling2D" "off" in /etc/X11/xorg.conf or the environment variable R600_DEBUG=no2d (or even R600_DEBUG=notiling) for chromium work around the problem? > dpm is, and has been working flawlessly thank you very much, cutting my > desktop's power consumption from 130W to 90W :) over the last year that's > saved at least the price of the beer I owe you for the dpm work, Michel :) Sounds great, but I haven't done any DPM work, I think that beer would have to go to Alex. :)
